Exploring the Effects of Sensorimotor Training and Relaxation Therapy on Postural Control, Balance, Sleep, and Stress in Sedentary Young Adults: Rationale, Design, and Methodology.

Postural control (PC) and sleep are critical in several aspects of health. Poor sleep negatively influences PC and balance, which is necessary for performing various tasks, from reaching to mobility. Moreover, sleep disturbances and consequent PC and balance deterioration are associated with job accidents, traffic accidents, falls, and injuries. Healthy adults who have inadequate sleep show a decline in optimal functioning, even in the absence of medical illnesses. This suggests that getting enough sleep, both in duration and quality, is essential to maintain optimal health. Moreover, inadequate sleep has also been observed to have a bidirectional relationship with stress levels. However, there is insufficient evidence regarding the impact of non-pharmacological treatments to improve PC, sleep, and stress in the sedentary young adult (YA) population. This article describes the protocol for a study to investigate the effects of sensorimotor training and relaxation therapy on various static and dynamic PC tests, balance measures, and subjective and objective indices of sleep and stress among sedentary YAs with impaired sleep quality. The protocol is also designed to evaluate the effect of these therapies on fatigue, salivary cortisol levels, anxiety, and depression. Methods for assessing the sleep architecture, static and dynamic PC, balance, and stress are described along with the methods of scoring with the primary goal of providing a standardized set of assessment and scoring procedures according to the latest guidelines and gold-standard techniques and measures that can be used reliably at different laboratories. © 2024 Wiley Periodicals LLC.
